according to this Live Wallpaper is destroyed and recreated another when you have to load the models supposed to do it but I want to rotate the long Object3D java.lang.NullPointerException error

Here I load the code where the models. and where broken waiting. Any advice on how to perform the load or which load models. From already thank you

Code load model:

Code: [Select]

public void onSurfaceChanged(GL10 gl, int w, int h) {
if (fb != null) {
fb.dispose();
}
fb = new FrameBuffer(gl, w, h);

world = new World();
world.setAmbientLight(20, 20, 20);

sun = new Light(world);
sun.setIntensity(250, 250, 250);

TextureManager.getInstance().addTexture("texture", texFuego);

cube = Object3D.mergeAll(Loader.load3DS(getResources().getAssets().open("modelos/parlante1.3ds"), 1));
cube.build();
cube.strip();
cube.forceGeometryIndices(true);
cube.rotateZ(-1.5f);

world.removeAllObjects();
world.addObject(cube);


Camera cam = world.getCamera();
cam.moveCamera(Camera.CAMERA_MOVEOUT, 50);
cam.lookAt(cube.getTransformedCenter());


SimpleVector pos = new SimpleVector(0, 0, 15);
part = new ParticleSystem(world, pos, 30, 30, "texture", 20,1, 10, 0);
part.SetMaxScale(4f);
part.setMaxDir(new SimpleVector(0.1f, 1f, 0.1f));


SimpleVector sv = new SimpleVector();
sv.set(cube.getTransformedCenter());
sv.y -= 100;
sv.z -= 100;
sun.setPosition(sv);
MemoryHelper.compact();

if (master == null) {
Logger.log("Saving master Activity!");
master = MyWallpaperService.this;
}

}
Drawing code:

Code: [Select]

public void onDrawFrame(GL10 gl) {
// (int)(Math.random() * (9-1)+1)

long endTime = System.currentTimeMillis();
float timeDiff = (endTime - startTime) / 1000.0f;
startTime = endTime;

fb.clear(new RGBColor(255, 255, 255));

rotarObjeto(cube, rotacion);


world.renderScene(fb);
world.draw(fb);

//particleSystem
part.Update(timeDiff);

fb.display();

}

public void rotarObjeto(Object3D objeto, int Num) {
objeto.rotateX(0);
objeto.rotateY(0);
objeto.rotateZ(0);

if (contador > 63 || contador == 0) {
rotacion = (byte) (Math.random() * (9 - 1) + 1);
contador = 0;
}
contador++;

float Speed = 0.1f;
switch (Num) {
case 1:
objeto.rotateX(Speed);
break;
case 2:
objeto.rotateY(Speed);
break;
case 3:
objeto.rotateZ(Speed);
break;
case 4:
objeto.rotateX(Speed);
break;
case 5:
objeto.rotateY(Speed);
break;
case 6:
objeto.rotateZ(Speed);
break;
case 7:
objeto.rotateX(Speed);
objeto.rotateY(Speed);
break;
case 8:
objeto.rotateX(Speed);
objeto.rotateZ(Speed);
break;
case 9:
objeto.rotateY(Speed);
objeto.rotateZ(Speed);
break;
}
}



It works rather than to start running the problem arises when I turn the screen from portrait to landscape and viceverza

[EgonOlsen]

Somehow something is null in your rotarObjeto method. Which line is 365? That's a problem with the way in which you are dealing with the screen rotation, it's not the fault of the engine...just add some more debug output to see what actually happens there.
